I get about 4 hours of battery life doing stuff like web browsing. Brightness at 100%, max power limit at the default 9W TDP in the BIOS, both USB ports used. The Windows 10 battery estimate is hopelessly inaccurate.
No idea how everyone else gets 7-8 hours.
It’s one disappointing aspect of this laptop .

I get around 5:30 hours, but I usually have the brightness at 40% and do not use the usb ports. Mostly just surfing the net and watching videos.

I would say ‘expected’ rather than disappointing considering the price. Most laptops below £500 only get several hours of on time out of batteries. 4-5 is good at this price point (very good really) – I was just questioning 8 hrs as being a bit odd?

My Acer Chromebook 720 would easily get about 8 hours when the battery was new.
My old Acer Timeline 14″ laptop (Windows) also got about the same when new.
4-5 hours is really poor IMO as that doesn’t even get you through a full day. I find that I have to plug this in half way through the day, every day…

In your Acer 720 what is the CPU performance, amount of RAM, eMMC/SSD size, and size and resolution of the screen? I’m guessing ALL of those are significantly below that of the EZB3 Pro making the battery life difference completely understandable, if not acceptable.

That’s a fair point but then I think of the 10 hours+ I get from the noticeably more powerful, brighter screen’d Dell XPS 13 I use at work and realise the massive difference between a laptop with good battery life and one without!
October 12, 2017 at 3:51 pm #73292I have a v2 EZB3 Pro. I don’t think I actually get 8 hours more likely 6 or 7. For the most part, I am just web browsing and doing office work with screen brightness at 25%.
Anyways here is what the battery report shows for “battery life estimates”.

I have the power limit unlimited.
October 13, 2017 at 8:09 am #73357Do you work in a darkened room? I don’t understand how anyone can work with 25% brightness during the day as the the maximum brightness of this panel is already pretty low at only about 200nits. 25% would be 50nits!!
October 19, 2017 at 6:08 pm #73656I wonder if a couple of people who report 5 to 8 hrs battery life would mind posting the properties of their batteries using HWinfo64.
Here is mine below (my battery life by the Win10 report and BatteryBar 3.6.6 is about 4.5hrs).

What are you mostly using it for? some task which seems simple might actually be really hard on your cpu especially for a low end cpu which will need to run at turbo speed most of the time.
other than that there are no simple ways of telling if the battery is failing, the easiest method would be to use a multi-meter to determine if there is a huge variation between the cells but other than that you will need specialized equipment.

123456789? Sounds genuine! LOL.
October 22, 2017 at 9:20 pm #73799I get about 6 to 7 hours at 35% brightness just browsing.
October 25, 2017 at 8:22 pm #73928Yes me too, 7-8 hours 25%-50%. Yes at first I thought the brightness is not that high but due to matte display it is actually sufficient!
